Quantum open system identification via global optimization: Optimally accurate Markovian models of open systems from time-series data
Zakhar Popovych, Kurt Jacobs, Georgios Korpas +2
Accurate models of the dynamics of quantum circuits are essential for optimizing and advancing quantum devices. Since first-principles models of environmental noise and dissipation…
Asymmetric Tunneling of Bose-Einstein Condensates
Dusty R. Lindberg, Naceur Gaaloul, Lev Kaplan +5
In his celebrated textbook, , Landau argued that, for single particle systems in 1D, tunneling probability remains the same for…
Quantum Dynamical Emulation of Imaginary Time Evolution
Jacob M. Leamer, Alicia B. Magann, Denys I. Bondar +1
We introduce a constructive method for mapping non-unitary dynamics to a weighted set of unitary operations. We utilize this construction to derive a new correspondence between rea…
Spectral gaps of two- and three-dimensional many-body quantum systems in the thermodynamic limit
Illya V. Lukin, Andrii G. Sotnikov, Jacob M. Leamer +2
We present an expression for the spectral gap, opening up new possibilities for performing and accelerating spectral calculations of quantum many-body systems. We develop and demon…
Robust Free-Space Optical Communication Utilizing Polarization
Nicholas J. Savino, Jacob M. Leamer, Ravi K. Saripalli +3
Free-space optical (FSO) communication can be subject to various types of distortion and loss as the signal propagates through non-uniform media. In experiment and simulation, we d…
